South Suburb (2009)

Yanjun Hu, Li Gao, Xiaoping Ma, Zhigeng Pan, Li Li

A public-key asymmetric robust watermarking algorithm based on signal with special correlation characteristic is proposed in this paper. This algorithm is designed to permit pubic watermark detection...

Application of MultiScale Hidden Markov Modeling Wavelet Coefficients to fMRI Activation Detection (2008)

Fangyuan Nan, Yaonan Wang, Xiaoping Ma

Problem Statement: The problem of detection of functional magnetic resonance images (fMRIs), that is, to decide active and nonactive regions of human brain from fMRIs is studied in this paper. fMRI...

Impaired Male Sexual Behavior in Activin Receptor Type II Knockout Mice1 (2005)

Xiaoping Ma, Andrea Reyna, Shailaja K. Mani, Martin M. Matzuk, T. Rajendra Kumar

Integration of multiple hormonal and neuronal signaling pathways in the medial preoptic area (mPOA) is required for elicitation of male sexual behavior in most vertebrates. Perturbation of nitric...

A Single-Chain Tetradomain Glycoprotein Hormone Analog Elicits Multiple Hormone Activities In Vivo1 (2005)

Vicenta Garcia-Campayo, Irving Boime, Xiaoping Ma, Dorit Daphna-Iken, T. Rajendra Kumar

We previously demonstrated that genetically linking one or more of the glycoprotein hormone-specific β subunit genes to the common α subunit resulted in single-chain analogues that were bioactive...

Ectopic expression of A-myb in transgenic mice causes follicular hyperplasia and enhanced B lymphocyte proliferation

DeRocco, Susan E., Iozzo, Renato, Ma, XiaoPing, Schwarting, Roland, Peterson, David, Calabretta, Bruno

The A-myb gene is a transcription factor that shares structural and functional similarities with the v-myb oncogene. To date, v-myb is the only myb gene directly implicated in tumorigenesis, a...

Targeted disruption of luteinizing hormone β-subunit leads to hypogonadism, defects in gonadal steroidogenesis, and infertility

Ma, Xiaoping, Dong, Yanlan, Matzuk, Martin M., Kumar, T. Rajendra

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) act on gonadal cells to promote steroidogenesis and gametogenesis. Clarifying the in vivo roles of LH and FSH permits a feasible...
